Electromagnet Uses in Physics Lab
Introduction The electromagnet is a combination of two words electro + magnet. The second one is clear, this is the magnet but what about first (electro)? What does it indicate electron or electricity? Let me know about, just think? Yes, it is electricity that flows in a conductor. But now the question is why magnet ...
